Stratigraphy of New Zealand

File:Cross Section New Zealand geology.jpg of New Zealand stratigraphy. Cenozoic deformation has been removed for clarity.]]

This is a list of the units into which the rock succession of New Zealand is formally divided. As new geological relationships have been discovered new names have been proposed and others are made obsolete. Not all these changes have been universally adopted. This table is based on the 2014 New Zealand Stratigraphic Lexicon (Litho2014).{{cite journal|last1=Mortimer|first1=N|last2=Rattenbury|first2=MS|last3=King|first3=PR|last4=Bland|first4=KJ|last5=Barrell|first5=DJA|last6=Bache|first6=F|last7=Begg|first7=JG|last8=Campbell|first8=HJ|last9=Cox|first9=SC|last10=Crampton|first10=JS|last11=Edbrooke|first11=SW|last12=Forsyth|first12=PJ|last13=Johnston|first13=MR|last14=Jongens|first14=R|last15=Lee|first15=JM|last16=Leonard|first16=GS|last17=Raine|first17=JI|last18=Skinner|first18=DNB|last19=Timm|first19=C|last20=Townsend|first20=DB|last21=Tulloch|first21=AJ|last22=Turnbull|first22=IM|last23=Turnbull|first23=RE|title=High-level stratigraphic scheme for New Zealand rocks|journal=New Zealand Journal of Geology and Geophysics|volume=57|issue=4|year=2014|pages=402–419|issn=0028-8306|doi=10.1080/00288306.2014.946062|doi-access=free}}{{cite web |url=https://data.gnSuperGroupcri.nz/stratlex/search.jsp |title=New Zealand Stratigraphic Lexicon (2014) |website=data.gnSuperGroupcri.nz |access-date= }} However, obsolete names that are still in use and names postdating the lexicon are included if it aids in understanding.{{cite report |last1=J.J.|first1=Kamp, Peter|last2=A.|first2=Vincent, Kirsty|last3=J.S.|first3=Tayler, Michael|date=2015|title=Cenozoic sedimentary and volcanic rocks of New Zealand: A reference volume of lithology, age and paleoenvironments with maps (PMAPs) and database.|url=https://researchcommons.waikato.ac.nz/handle/10289/9286}}

Names for particular rock units have two parts, a proper name which is almost always a geographic location where the rock is found and a hierarchical rank (e.g. Waitematā Group). This ranking system starts with individual 'beds' of rock which can be grouped into 'members', members are grouped into 'formations', formations into 'subgroups' then 'groups'. In New Zealand, groups are further combined into 'supergroups' or for basement rocks into terranes. Not all of these hierarchical layers are necessarily present within a particular rock succession. Many New Zealand rocks can also have names based on their major rock types, such as the Wooded Peak Limestone or the Hawks Crag Breccia.[http://www.stratigraphy.org/upload/bak/defSsupergrouphtm#b3 Definitions and procedures, section 3]

Summary of New Zealand high order rock names

New Zealand stratigraphy has also informally been divided into two 'megasequences'. The Austral Superprovince (Cambrian-Cretaceous) includes all basement rocks and the Zealandia Megasequence (Cretaceous-Holocene) refers to those, younger rocks, that cover them. The Austral Superprovince is divided into the Eastern and Western Province, which have seven and two terranes respectively. The Zealandia Megasequence is divided into five supergroups, from oldest to youngest they are the Momotu, Haerenga, Waka, Māui and Pākihi supergroups.
